In addition to the performance features of graphite ferrules
detailed above, the significant advantage of one piece ferrules
is they do not require a back ferrule.
They can be used in Swagelok type fittings and in SGE fit-
tings that use the SGE extended capture nuts (SSNE-16,
SSNE-8, SSNE-4).
SGE OGF - One Piece - combination front and back Graphite Ferrule
S
GE graphite ferrules are 99.95% pure graphite and are
extremely easy to use, for obtaining reliable leak free
connections.
Graphite ferrules can be used with all types of tubing including
glass and are extensively used in SGE injection systems, valves,
fittings and unions. Because graphite does not stick or bind onto the
tubing, graphite may be removed and reused.
Note:
These ferrules are physically soft and for best results
should be tightened "finger tight" plus "half a turn" at a time until gas
tight. This method will ensure the ferrule is reusable and prevent
overtightening which will cause the graphite to flow.
GFF type ferrules may be used with Swagelok type unions, but
back ferrules are required. Back ferrules are not necessary with
SGE unions.
